NEW QUESTION # 33
Your ArubaoS solution has detected a rogue AP with Wireless intrusion Prevention (WIP). Which information about the detected radio can best help you to locate the rogue device?
- A. the match type
- B. the confidence level
- C. the detecting devices
- D. the match method
Answer: C
Explanation:
When an ArubaOS solution detects a rogue AP with Wireless Intrusion Prevention (WIP), the most crucial information that can help locate the rogue device is the detecting devices. This is because the detecting devices can provide the physical location or the network topology context where the rogue AP has been detected1.
The detecting devices are typically the Air Monitors (AMs) or Access Points (APs) in the network that have identified the rogue AP's presence. These devices can provide information such as the signal strength and the direction from which the rogue AP's signals are being received. By triangulating this information from multiple detecting devices, it becomes possible to pinpoint the physical location of the rogue AP2.
Additionally, the detecting devices can log events and alerts that can be reviewed to understand the rogue AP's behavior, such as the channels it is operating on and the potential impact on the authorized wireless network1. This information is vital for network administrators to quickly and effectively respond to the threat posed by the rogue AP.
In contrast, the match method (A) and match type relate to how the rogue AP is classified and identified by the system, which is useful for classification but not for physical location. The confidence level (D) indicates the system's certainty in the classification but does not aid in locating the device2.
NEW QUESTION # 34
A company has an ArubaOS controller-based solution with a WPA3-Enterprise WLAN. which authenticates wireless clients to Aruba ClearPass Policy Manager (CPPM). The company has decided to use digital certificates for authentication A user's Windows domain computer has had certificates installed on it However, the Networks and Connections window shows that authentication has tailed for the user. The Mobility Controllers (MC's) RADIUS events show that it is receiving Access-Rejects for the authentication attempt.
What is one place that you can you look for deeper insight into why this authentication attempt is failing?
- A. the reports generated by Aruba ClearPass Insight
- B. the Alerts tab in the authentication record in CPPM Access Tracker
- C. the packets captured on the MC control plane destined to UDP 1812
- D. the RADIUS events within the CPPM Event Viewer
Answer: D
Explanation:
When an authentication attempt for a user's Windows domain computer is failing on a WPA3-Enterprise WLAN and the Mobility Controller is receiving Access-Rejects, one place to look for deeper insight is the RADIUS events within the CPPM Event Viewer. ClearPass Policy Manager (CPPM) logs all RADIUS authentication events, and the Event Viewer would show detailed information about why a particular authentication attempt was rejected. This could include reasons such as incorrect credentials, expired certificates, or policy mismatches. The CPPM Event Viewer is an essential troubleshooting tool within ClearPass to diagnose authentication issues, as indicated in the ClearPass Policy Manager documentation.
NEW QUESTION # 35
What is one of the roles of the network access server (NAS) in the AAA framewonx?
- A. It authenticates legitimate users and uses policies to determine which resources each user is allowed to access.
- B. It enforces access to network services and sends accounting information to the AAA server
- C. It determines which resources authenticated users are allowed to access and monitors each users session
- D. It negotiates with each user's device to determine which EAP method is used for authentication
Answer: B
Explanation:
In the AAA (Authentication, Authorization, and Accounting) framework, the role of the Network Access Server (NAS) is to act as a gateway that enforces access to network services and sends accounting information to the AAA server. The NAS initially requests authentication information from the user and then passes that information to the AAA server. It also enforces the access policies as provided by the AAA server after authentication and provides accounting data to the AAA server based on user activity.
References:
Technical literature on AAA protocols which often includes a description of the roles and responsibilities of a Network Access Server.

NEW QUESTION # 39
Refer to the exhibit.
This Aruba Mobility Controller (MC) should authenticate managers who access the Web Ul to ClearPass Policy Manager (CPPM) ClearPass admins have asked you to use RADIUS and explained that the MC should accept managers' roles in Aruba-Admin-Role VSAs Which setting should you change to follow Aruba best security practices?
- A. Change the default role to "guest-provisioning"
- B. Disable local authentication
- C. Change the local user role to read-only
- D. Clear the MSCHAP check box
Answer: B
Explanation:
For following Aruba best security practices, the setting you should change is to disable local authentication.
When integrating with an external RADIUS server like ClearPass Policy Manager (CPPM) for authenticating administrative access to the Mobility Controller (MC), it is a best practice to rely on the external server rather than the local user database. This practice not only centralizes the management of user roles and access but also enhances security by leveraging CPPM's advanced authentication mechanisms.
References:
Aruba Networks official best practice documentation, which recommends centralized authentication for administrative access.
Security standards and guidelines that promote the use of external RADIUS servers for authentication purposes.
NEW QUESTION # 40
Which is a use case for enabling Control Plane Policing on Aruba switches?
- A. to encrypt traffic between tunneled node switches and Mobility Controllers (MCs)
- B. to prevent unauthorized network devices from sending routing updates
- C. to mitigate Denial of Service (Dos) attacks on the switch
- D. to prevent the switch from accepting routing updates from unauthorized users
Answer: C
Explanation:
Control Plane Policing (CoPP) on Aruba switches is used to mitigate Denial of Service (DoS) attacks on the switch. CoPP allows network administrators to restrict the impact of control plane traffic on the switch's CPU, thereby protecting network stability and integrity. By setting rate limits and specifying allowed traffic types, administrators can prevent malicious or malformed packets from overwhelming the switch's control plane, which could otherwise lead to a DoS condition and potentially disrupt network operations. This use case of CoPP is detailed in Aruba's network management documentation, where best practices and configurations to protect against DoS attacks are discussed.
NEW QUESTION # 41
A company has an ArubaOS solution. The company wants to prevent users assigned to the "user_group1" role from using gaming and peer-to-peer applications.
What is the recommended approach for these requirements?
- A. Create ALGs for the gaming and peer-to-peer applications, and deny the "user_group1" role on the ALGs.
- B. Make sure DPI is enabled, and add application rules that deny gaming and peer-to-peer applications to the "user_groupr role.
- C. Add access control rules to the "user_group1" role, which deny HTTP/HTTPS traffic to IP addresses associated with gaming and peer-to-peer applications.
- D. Create service aliases for the TCP ports associated with gaming and peer-to-per applications, and use those aliases in access control rules for the "user_group" rules.
Answer: B
Explanation:
The recommended approach for preventing users in the "user_group1" role from using gaming and peer-to-peer applications in an ArubaOS environment is to enable Deep Packet Inspection (DPI) and add application rules that specifically deny access to these types of applications for the role. DPI allows the network system to analyze the content of network traffic in real time and apply policies based on what it detects, including blocking specific applications like gaming and peer-to-peer sharing. This capability is essential for effectively managing application usage on the network and ensuring compliance with organizational policies. Application-specific rules provide precise control over the network traffic by identifying the application regardless of the network port used, making it a more effective method than blocking based on ports or IP addresses.
NEW QUESTION # 42

- C. WPA3-Personai is more resistant to passphrase cracking Because it requires passphrases to be at least 12 characters
- D. WPA3-Personal is more complicated to deploy because it requires a backend authentication server
Answer: A
NEW QUESTION # 45
Which endpoint classification capabilities do Aruba network infrastructure devices have on their own without ClearPass solutions?
- A. ArubaOS-Switches can use DHCP fingerprints to construct detailed endpoint profiles.
- B. ArubaOS devices can use a combination of DHCP fingerprints, HTTP User-Agent strings, and Nmap to construct endpoint profiles.
- C. ArubaOS-CX switches can use a combination of active and passive methods to assign roles to clients.
- D. ArubaOS devices (controllers and lAPs) can use DHCP fingerprints to assign roles to clients.
Answer: D
Explanation:
Without the integration of Aruba ClearPass or other advanced network access control solutions, ArubaOS devices (controllers and Instant APs) are able to use DHCP fingerprinting to assign roles to clients. This method allows the devices to identify the type of client devices connecting to the network based on the DHCP requests they send. While this is a more basic form of endpoint classification compared to the capabilities provided by ClearPass, it still enables some level of access control based on device type. This functionality and its limitations are described in Aruba's product documentation for ArubaOS devices, highlighting the benefits of integrating a full-featured solution like ClearPass for more granular and powerful endpoint classification capabilities.
NEW QUESTION # 46
You are deploying an Aruba Mobility Controller (MC). What is a best practice for setting up secure management access to the ArubaOS Web UP
- A. Avoid using external manager authentication tor the Web UI.
- B. Change the default 4343 port tor the web UI to TCP 443.
- C. Make sure to enable HTTPS for the Web UI and select the self-signed certificate Installed in the factory.
- D. Install a CA-signed certificate to use for the Web UI server certificate.
Answer: D
Explanation:
For securing management access to the ArubaOS Web UI of an Aruba Mobility Controller (MC), it is a best practice to install a certificate signed by a Certificate Authority (CA). This ensures that communications between administrators and the MC are secured with trusted encryption, which greatly reduces the risk of man-in-the-middle attacks. Using a CA-signed certificate enhances the trustworthiness of the connection over self-signed certificates, which do not offer the same level of assurance.References:
ArubaOS documentation on management access security.
NEW QUESTION # 47

NEW QUESTION # 49
You configure an ArubaOS-Switch to enforce 802.1X authentication with ClearPass Policy Manager (CPPM) denned as the RADIUS server Clients cannot authenticate You check Aruba ClearPass Access Tracker and cannot find a record of the authentication attempt.
What are two possible problems that have this symptom? (Select two)
- A. The RADIUS shared secret does not match between the switch and CPPM.
- B. Clients are configured to use a mismatched EAP method from the one In the CPPM service.
- C. CPPM does not have a network device defined for the switch's IP address.
- D. Clients are not configured to trust the root CA certificate for CPPM's RADIUS/EAP certificate.
- E. users are logging in with the wrong usernames and passwords or invalid certificates.
Answer: A,C
Explanation:
If clients cannot authenticate and there is no record of the authentication attempt in Aruba ClearPass Access Tracker, two possible problems that could cause this symptom are:
The RADIUS shared secret does not match between the switch and CPPM. This mismatch would prevent the switch and CPPM from successfully communicating, so authentication attempts would fail, and no record would appear in Access Tracker.
CPPM does not have a network device profile defined for the switch's IP address. Without a network device profile, CPPM would not recognize authentication attempts coming from the switch and would not process them, resulting in no logs in Access Tracker.
The other options are incorrect because:
Users logging in with the wrong credentials would still generate an attempt record in Access Tracker.
Clients configured to use a mismatched EAP method would also generate an attempt record in Access Tracker.
Clients not configured to trust the root CA certificate for CPPM's RADIUS/EAP certificate might fail authentication, but the attempt would still be logged in Access Tracker.
NEW QUESTION # 50
What is a use case for implementing RadSec instead of RADIUS?
- A. A university wants to protect communications between the students' devices and the network access server.
- B. A school district wants to protect messages sent between RADIUS clients and servers over an untrusted network.
- C. A corporation wants to implement EAP-TLS to authenticate wireless users at their main office.
- D. A organization wants to strengthen the encryption used to protect RADIUS communications without increasing complexity.
Answer: B
Explanation:
RadSec (RADIUS over TLS) is a protocol for transporting RADIUS messages over TLS-encrypted TCP/IP networks. The primary use case for implementing RadSec instead of traditional RADIUS is to protect RADIUS communications, particularly when those messages must travel across an untrusted network, such as the internet. RadSec provides confidentiality, integrity, and authentication for RADIUS traffic between clients and servers which may not be within a single secure network. In the case of a school district that wants to ensure the security of messages sent between RADIUS clients and servers over potentially insecure networks, RadSec would be the appropriate choice.

Refer to the exhibit.
Device A is establishing an HTTPS session with the Arubapedia web sue using Chrome. The Arubapedia web server sends the certificate shown in the exhibit What does the browser do as part of vacating the web server certificate?
- A. It uses the public key in the DigCert root CA certificate to check the certificate signature
- B. It uses the public key in the DigCen SHA2 Secure Server CA certificate to check the certificate's signature.
- C. It uses the private key in the Arubapedia web site's certificate to check that certificate's signature
- D. It uses the private key in the DigiCert SHA2 Secure Server CA to check the certificate's signature.
Answer: B
Explanation:
When a browser, like Chrome, is validating a web server's certificate, it uses the public key in the certificate's signing authority to verify the certificate's digital signature. In the case of the exhibit, the browser would use the public key in the DigiCert SHA2 Secure Server CA certificate to check the signature of the Arubapedia web server's certificate. This process ensures that the certificate was indeed issued by the claimed Certificate Authority (CA) and has not been tampered with.
References:
